To all wiwm imayoorwem: c

.Be it known that 1, BENJAMIN Morgan,

e citizen of the United States, residing at;

Jersey City, in the county of fludsongfiiate or New Jersey, have invented certain irew end usefulv Improvements in Air'Brakes for Locomotiveflrenes; and I" do hereby de clerethe following to he efiull, clear, and 'exeoi; description of the invention such as I 19 will enable others skilled in the'art to which i itfappertains to make and use the se ne.

Thie im'ent-ron relates to an air brake 'Jtor locomotive cranes.

An object of the invention resides; in the plOVlSlQfl of an 311 brakemochanism by means of which the wheels of av loeonm'eive erene may be locked. I

A further object of the invention residee in so constructing the device that fit/will operate irrespective of the position. of the rotating base wiizh 'reiet-ion to the oer body.

A further object of the invention resides in the provision 01": e coxitroiling velreton the rotating within. minveoierm reach of *zhe opere-tor soighet the brakes; may beep ,g iliedor released. A still further object of e'he inveii'ion resides in the provision of a novel neeeheniem for hrmsmittimg iii-e air from the pump to thehreke mechanism; d

YWith these other object: in 'vie'w' su h eewill appear as my description LROgiESSGfi, my invention comprises the comhiziatioi'x and arrangement of parts set fore in and falling within the scope of the eppe ed ed claim.

In the drawin z- Figure 1 is all elevetionel View of my ('ievice showing the some mounted} on 1:-

section however; v E1 2 is a fregmeuml secisional 'vlew showmg the manner 111 which the err conto thecar body Fig. 3 is e horizontel sectional View c through the center or king pin of flee rotatiu%base,'end I ii'g. his a. fragmentel detail. I :In the drawing I have illustretede com 7 e ntionel form of looomotive' crane and have shown only such .perto thereof as are necessary to the understanding of myfinve b eon. This crane includes 11 travel shaft 5 extends on above izhe geer 6 1 ducting pipe from the meeting tebly mounted so that the-brakesmafybe I broadlyja; rotsr'c-c the 5 ingbese 1 and e cerbodyQ, the latter being 'mpported by suitable wheels 3: This beee 1" is rotatably mounted. on a center orfking pin carried-by the body 2 through which piri the upper end of which a beveled gear 6 is secured, which 0 gear meshes with beveled drive gears 7 on the actuating shaft 8. On the lower end of the travel shaft 5 is secured a beveled gear 9 which meshes with a gear on the car body 2 so that the lease may be rotated on the body. The gearing used and above described is similar to that ordinarily used in locomotive cranes and a more detailed description is therefore not deemed necessary. in order that the movement of the wheels may be arrested I have provided the same with brakes, not shown, which brakes are applied by means of suitable operating mechanism 10 which is indicated conventionally as the details of construction form no pert of the present invention. It is only essential that this operating mechanism be actuated. by air. w

in order that ihe said mechanism may be supplied Wiid'l air I have formed a hold 11 in the travel shaft 5 which extends axially thereof and from end to, end, Extending ehrough this hole 11 is a pipe 12 which pipe likewise extends through axially arranged' holes in the gears 6 and 9 and is connected at one end to the brake operating mechanism, 16. The upper portion of this pipe extends above the gear '6 which is located ebov-e the brake operating mechanism 10. r The upper portion of this pipe extends which is located above rotating base and is connected to a Qhle Storage tank 12 end a) pump 13, r pump is geared to the 0, erating heroism the base. Interpo ated in pipe heme e11 the tank and the gear M a three-We velve 12 of any desired neruoeioe which. valve is located withix'i re he reach of the. operator endjgpn liq-icing these 1. I e iower end of the pipe 12-is provided with e :Wiveled connection 14 so that when the base rotates on the car bod the portion of the pipe which exten s .upwardly through the travel shaft mill rotate therewith. Itwivill thus'be seen is at I' have ex- 7 tended the air supply pipe through the oenicer or king pin onwhioh the base is roteapplied irrespective of the riaeition 0 base with relation to the car" (1 particular embodiment ofmy invention it has merely been for the sake of convenience and I do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made in the minor details of construction without departing from the spirit of the invention or exceeding the scope of the claim.

\Vhat I claim, is

The combination with a locomotive crane including a car body, of a king pin extending upwardly therefrom, a travel shaft r0- tatably mounted in the king pin, a rotatable -base mounted on the king pin, mechanism for applying brakes to the cur wheels, a pipe extending longitudinally through the travel shaft, and a pump mounted on the base rigidly and connected to the upper end of the pipe, the lower end of the pipe being connected to the brake applyin mechanism.

In testimony whereof, I a 1! my signature, in the presence of two witnesses.
